"Browser no longer supported" error, even though Chrome is available

[ghost]

When I start the Classroom Assistant it shows me the normal login screen.

When I click on the 'Log In With Classroom' button I get the following error:

I do have Chrome installed and Chrome is my default browser. I'm also on Windows 10 so it's possible that it's trying to use IE (or Edge?) or something.

There's no clear way for me to change the browser that I'm using, at least within Classroom Assistant. I'm also not clear on how to check which browser it's actually using.

I am using the Edge Deflector App but since Chrome is my default browser I'm hoping that this will help things instead of making them worse :)

I spoke too soon - I am able to log in (after clicking on 'ignore').

It's worth noting that whatever browser Assistant is using didn't save my password (at least initially) so I had to go ask Chrome to show me my password (it was one of those auto-generated strong password things)

I got the same error just now, even though Chrome in its uptodate version is running on MacOS X Catalina. It appears to be cosmetic, since I was able to log in to the classroom anyway.
